Preparation and Functions of Self-healing Light-shielding Paints for Cable Cover

doi:10.7503/cjcu20190066

Abstract

Abstract: Self-healing light-shielding paints can not only reduce the photo-aging on the cable cover by ultro-violet, but also recover the micro-damage and hallrcuts on the surface of cable cover, improve the life of cable. In this paper, using nano particle of TiO₂ decorated by β-cyclodextrin(β-CD) as light-shielding agents, we developed a new light-shielding paint, the self-healing function of which was realized by inclusion interaction between β-CD and adamantane. This paint can stick on the PVC sample tightly and demonstrate a good hydrophobicity and low hydroscopicity. It has an excellent light-shielding ability on ultraviolet(>90%). Moreover, this paints had a good self-healing ability, the crack made by knife can recover at least three times and its tensile property can recover beyond 80%.
